Chinese Professional Ofdm Ofdma - Cable CPE, Data Modem, DOCSIS 3.1, 4xGE, SP440 – MoreLink Detail:

Product Detail

The MoreLink’s SP440 is a DOCSIS 3.1 Cable Modem supporting 2×2 OFDM and 32×8 SC-QAM to deliver a powerful high-speed Internet experience.

The SP440 is the perfect choice for cable operators who want to offer high-speed and economic broadband access to their customer base. It delivers speeds up to 4Gbps based on 4 Giga Ethernet ports over its DOCSIS interface. The SP440 allows MSOs to offer their customers various broadband applications such as telecommuting, HD, and UHD video on demand over IP connectivity to a small oce/home oce (SOHO), high-speed residential Internet access, interactive multimedia services, etc.

The SP440 is an intelligent device that enhances its basic data transmission features with IPv6 support, which makes it especially suitable for the transmission of data based on this protocol.
